Asp.net 5 成功发布后Web应用程序启动异常

Question

我有一个 Asp.net 5 Web 应用程序，它在开发中运行良好（从 Visual Studio 或 VS 代码我可以毫无问题地启动）。但是，在成功发布应用程序后，当尝试使用“web.cmd”启动网站时，会出现以下错误并阻止网站加载：

Application startup exception: System.IO.FileNotFoundException: Could not load file or assembly 'my-ng2-website' or one of its dependencies. The system cannot find the file specified.

我到处寻找解决方案。我不知道我缺少什么依赖。我试过了

deleting the package.lock.json

dnu restore

这是我对项目的 dnx 配置设置：

发布设置如下：

有人能读懂这些茶叶吗？

Answer 1

美好的一天。我们很少遇到这种类型的错误。它经常指向缺少的程序集（最常见的程序集）。检查所有必要的引用，设置为 Copy Local -> true，在大多数情况下都有帮助。如果 assemblies/references 设置为 Copy Local -> false，则不会包含在发布中。

希望对您有所帮助。

Answer 2

为了好玩，我将 "Compile source files into Nuget Package" 设置为 false。现在可以了。

为什么会这样，我不知道。但希望这会帮助别人。

Answer 3

此错误与位于项目目录（不是解决方案目录）中的 global.json 文件有关。如果你想发布带有编译选项的项目，确保将它添加到 project.json

中的 publishExclude

"publishExclude": [
  "**.user",
  "**.vspscc",
  "global.json"
],
